Nexperia USA Inc. 74LVT04D,112

Overview

74LVT04D,112 from Nexperia is a 3.3 V hex inverter IC with BiCMOS output drive, IOFF partial power-down protection, overvoltage-tolerant inputs up to 5.5 V, and guaranteed operation from –40 °C to +85 °C. It provides six independent inverting buffers for logic-level translation and bus isolation in mixed-voltage digital systems.

For engineers reviewing the 74LVT04D,112 datasheet, 74LVT04D,112 pinout, 74LVT04D,112 application, or 74LVT04D,112 equivalent, key selection criteria include its 2.7–3.6 V supply range, ±32 mA output drive, IOFF-enabled hot-swap capability, and SO14 (SOT108-1) package compatibility with legacy 74-series footprints.

Technical Context

The 74LVT04D implements six identical CMOS-input / BiCMOS-output inverting gates with rail-to-rail input tolerance and active high-impedance control during power-down via IOFF circuitry. Each gate operates with propagation delays as low as 1.0 ns (tPLH/tPHL, typ. at VCC = 3.3 V).

It supports direct TTL-level interfacing while maintaining 3.3 V core logic compatibility, and features latch-up immunity >500 mA per JESD78 Class II Level B. Input clamping and ESD protection (HBM >2000 V, CDM >1000 V) enable robust operation in noisy industrial environments.

Key Specifications

FAQ

Does 74LVT04D,112 support true 5 V input logic levels while operating at 3.3 V?

Yes. Its inputs are overvoltage tolerant up to +5.5 V regardless of VCC state, allowing direct connection to 5 V logic families without level-shifting circuitry. This is confirmed in Table 5 (VI max = 5.5 V) and Section 2 features.

What happens to the outputs when VCC is disconnected or at 0 V?

When VCC = 0 V, the IOFF circuitry forces all six outputs into a high-impedance state, limiting off-state current to ±100 μA maximum (Table 6). This prevents damaging back-current flow from live 5 V buses into the unpowered device.

Is the SO14 (SOT108-1) package of 74LVT04D,112 compatible with standard 74HC04 footprints?

Yes. The SOT108-1 package has identical 14-pin SOIC dimensions (3.9 mm body width, 1.27 mm pitch) and pinout as industry-standard 74HC04, enabling drop-in replacement in existing designs-verified in Figure 4 and Table 1.

How does 74LVT04D,112 differ from standard 74LVC04 in terms of bus interface capability?

Unlike 74LVC04, the 74LVT04D,112 includes IOFF and overvoltage-tolerant inputs, enabling safe connection to live 5 V buses during partial power-down. Its BiCMOS output also delivers higher sink current (32 mA vs. 24 mA), improving fan-out in noisy industrial environments.
